9.2.3 Rate (2.3.)
Note
Default settings in the parameter tables are indicated with an asterisk (*) unless explicitly
stated.
Note
•
The following three rate parameters work in conjunction, and are affected by Response
Rate (set in the
Quick Start (Page 59)).
•
Fill Rate per Minute (2.3.1.) (Page 174), Empty Rate per Minute (2.3.2.) (Page 174), and
Damping Filter (2.3.3.) (Page 174) automatically update when Response Rate is altered,
but any change to these parameters will supersede a Quick Start (Page 59) set
previously through the wizard.
•
For more information, see Measurement Response (Page 296).
9.2.3.1 Fill Rate per Minute (2.3.1.)
Defines the maximum rate at which the reported level is allowed to increase. Allows you to
adjust the SITRANS LUT400 response to increases in the actual material level.
Options
Range: 0.000 to 99999.000 m/min
Default: 0.100 m/min
Enter a value slightly greater than the vessel’s maximum filling rate, in units per minute.
9.2.3.2 Empty Rate per Minute (2.3.2.)
Defines the maximum rate at which the reported level is allowed to decrease. Adjusts the
SITRANS LUT400 response to decreases in the actual material level.
Options
Range: 0.000 to 99999.000 m/min
Default: 0.100 m/min
Enter a value slightly greater than the vessel’s maximum emptying rate, in units per minute.
9.2.3.3 Damping Filter (2.3.3.)
Use this to stabilize the reported level (displayed and analog output), due to level fluctuations
(such as a rippling or splashing liquid surface), defined in seconds.
Options
Range: 0.0 to 7200.0
Default: 100.0
